AVERAGE COSTS OF BOREHOLE DRILLING SERVICES IN KENYA

Borehole drilling is a common solution for individuals, businesses, and communities in Kenya to access a reliable source of water. However, the cost of drilling a borehole can vary significantly due to several factors. This article will explore the average costs of borehole drilling services in Kenya, with detailed explanations of what influences these prices.

AVERAGE COSTS OF BOREHOLE DRILLING IN KENYA

The cost of drilling a borehole in Kenya typically ranges between Ksh 1.5 million to Ksh 3 million. However, this cost can increase or decrease based on a variety of factors. Here is a breakdown of the typical expenses involved:

1. Survey and Site Assessment:

   • Before drilling begins, a hydrogeological survey must be conducted to determine the best location for the borehole. This survey usually costs between Ksh 50,000 and Ksh 100,000.

2. Drilling Costs:

   • Drilling is the most expensive part of the process. The cost is typically charged per meter and ranges from Ksh 6,000 to Ksh 9,000 per meter, depending on the location and the geological conditions.
   • The depth of boreholes can vary from 100 meters to 300 meters, meaning the total drilling cost alone can range from Ksh 600,000 to Ksh 2.7 million.

3. Casing and Installation:

   • Once the borehole is drilled, casing must be installed to prevent the hole from collapsing. PVC or steel casings are used, and the cost depends on the type of material and depth required. Casing can cost between Ksh 1,000 to Ksh 3,000 per meter.
   • For a borehole of 200 meters, the casing cost can range from Ksh 200,000 to Ksh 600,000.

4. Pumping Equipment:

   • A water pump is required to bring water to the surface. The type and capacity of the pump will depend on the borehole’s depth and the amount of water needed. Pump prices range from Ksh 50,000 to Ksh 300,000.

5. Water Testing:

   • After drilling, water quality tests are conducted to ensure the water is safe for use. Testing costs typically range from Ksh 15,000 to Ksh 30,000.

6. Borehole Cap and Cover:

   • The borehole must be capped to prevent contamination and accidents. A proper cap or cover can cost between Ksh 10,000 to Ksh 30,000.

FACTORS THAT DETERMINE THE COST OF BOREHOLE DRILLING

Several factors affect the cost of borehole drilling services in Kenya:

1. Location:

   • The geographical location of the drilling site plays a significant role in determining costs. Areas with hard rock formations or deeper water tables, such as Rift Valley and parts of Eastern Kenya, will have higher drilling costs compared to regions where water is closer to the surface.

2. Depth of the Borehole:

   • The depth required to reach water will significantly influence the cost. The deeper the borehole, the more expensive it becomes. Most boreholes in Kenya range from 100 meters to 300 meters.

3. Groundwater Availability:

   • The ease of accessing water also impacts the cost. In areas where water is abundant and easier to access, the drilling cost may be lower. Conversely, in arid and semi-arid areas, where water is scarce, the cost will be higher due to the increased drilling depth and complexity.

4. Type of Casing Material:

   • The type of casing material used (PVC or steel) can also affect the overall cost. Steel casing is generally more expensive but more durable, while PVC is cheaper but may not last as long.

5. Type of Pump:

   • The cost of the water pump varies depending on its capacity, brand, and the depth of the borehole. Solar-powered pumps, though more expensive upfront, can save on electricity costs in the long term.

6. Permits and Licenses:

   • Borehole drilling in Kenya requires permits from local authorities. These permits, including the Water Resources Authority (WRA) approvals, can add to the total cost, typically ranging between Ksh 50,000 and Ksh 100,000.

7. Accessibility of the Drilling Site:

   • Remote locations that are hard to reach may incur additional logistical costs, such as transportation of equipment and personnel, raising the total borehole drilling cost.

The cost of borehole drilling services in Kenya can range from Ksh 1.5 million to Ksh 3 million, depending on factors such as location, depth, and materials used. Understanding these factors will help you budget accurately and ensure that you get the best value for your investment in water access. Whether for personal use, agriculture, or commercial purposes, a borehole can be a long-term solution to water shortages, and the initial cost is an investment in reliable water supply
